Definitions

  • Weiser and Alfred Stapler ABSTRACT Jacketed gasket with at least one of its legs folded over for at the most half of its width, the fold being at a distance from the bend of the jacket which is at least equal to the thickness of the gasket in the noncompressed state.
  • Inserts such as annular disks, washers, wires of metal and synthetic resin, or other plastic material may be inserted into the fold.
  • the gasket after compression of its jacketed part has the advantage that no flowing out or squeezing out of the gasket material on compression or tightening of the gasket between the surfaces to be sealed can take place. Thus satisfactory sealing is guaranteed.
  • the present invention relates to gaskets and more particularly to partly enclosed or edge jacketed gaskets, i.e. to gaskets of a relatively soft material the edge parts of which are provided with and embraced by a reenforcingj'acket.
  • Sealing or packing sheets or gaskets consisting of a relatively soft material such as asbestos, preferably compressed asbestos, with natural or synthetic rubber as binder are jacketed and reenforced with jackets or borders preferably of sheet metal, especially at the edges which are exposed to considerable wear and tear.
  • the jackets or borders increase the mechanical strength of such sheet gaskets and protect them against destructive and injurious effects.
  • borders or edge jackets are especially useful for packing sheets or gaskets consisting of plastic material or asbestos in mixture with suitable binders when serving for packing and sealing separating or parting joints or gaps.
  • the borders or jackets exert not only a protective effect but they also improve local compressibility which can be adjusted within a wide range by varying the thickness of the bordering or jacketing sheet metal and the width of the jacket or border.
  • sheet gaskets or sealing and packing sheets composed, for instance, of asbestos and a binder, for instance, a synthetic resin, natural or synthetic rubber, and the like have the tendency to flow and to be squeezed out of the border or jacket area due to the high compression pressure.
  • a binder for instance, a synthetic resin, natural or synthetic rubber, and the like
  • the material forming the jacketed sheet gasket for instance, plastic or the asbestos mixture is squeezed out and flows out of the jacket. Due thereto the pressure on compressing the jacket and gasket is reduced to such an extent that proper sealing of the joint, for instance, against gases cannot be achieved with certainty.
  • the gasket according to the present invention is characterized by having at least one leg or extension of the border or jacket folded over and thus doubling the thickness of the jacket.
  • the folded over part of the leg should cover the remaining part of the leg only for a relatively small distance, i.e. not more than for about one-half, and preferably for about one-third to one-fourth of the width of the leg thus leaving part of said leg uncovered by the folded portion of the leg.
  • Folding is effected at a distance from the bend of the jacket which is at least equal to the thickness of the gasket in the noncompressed state.
  • the leg or extension of the border or jacket on the opposite side of the gasket may be folded over in the same manner and at the same distance from the bend of the jacket to the front edge of the folded part of the other leg or, respectively, to its rear edge or therebetween.
  • the unfolded leg on the opposite side of the gasket extends to about the middle or center line of said folded part of the other leg. In this manner squeezing out or flowing out of the gasket material within the area of the bordering or jacketing sheet metal is completely prevented or at least kept in permissible limits.
  • the effect is achieved that the clamping or compressing pressure causes upsetting compression or, respectively, pinching or squeezing together of the gasket material so that it cannot run out of the jacket. As a result thereof an undesired detrimental decrease in clamping or compression pressure is avoided.
  • the material used for bordering or jacketing the gasket may be any conventionally used bordering sheet metal, such as iron or soft sheet, stainless steel, Monel Metal, aluminum, copper, zinc, nickel, lead, and others. It may also be plastic material such as polytetrafluoro ethylene. Especially suitable have proved deep-drawing sheet metal or respectively, rigid, nondeforming synthetic resin, the shaped which is not affected by increased temperature.
  • Suitable resilient and relatively soft gasket materials are, for instance, asbestos which may be compressed and/or impregnated with suitable binder material such as natural or synthetic rubber, synthetic resins, and the like materials. Said binders may contain conventional filler materials.
  • the gasket material may be reenforced, for instance, by a preferably perforated sheet metal insert, a wire web, a web of wires and asbestos filaments, and the like. All such known soft and resilient packing or gasket materials, even if as such not yielding and not having the tendency to flow, do become plastic, or do yield under the clamping or compression pressure and at increased temperature so that they flow out or are squeezed out of the jacketed or bordered area of the gasket or that they yield and thus decrease the packing and sealing effect. Such flowing and yielding is prevented, at least to a large extent, by the present invention.
  • the jacketing or bordering sheet metal or plastic may be folded, or laid over, outwardly or inwardly.
  • inserts may be provided and inserted into the fold or, respectively, into one of the folds or in both folds, if present.
  • Said inserts are composed of noncompressible material, if it is desired to increase the clamping or compression pressure upon the jacketed part of the gasket. They may also consist of a flowable material, for instance, of a flowable synthetic resin, if additional microsealing is required.
  • the inserts may also have the form of discs or flanges, of rings, of wires and the like and may consist, for instance, of metal or of synthetic resin.
  • the inserts permit additional variations in the distribution of the clamping or compression pressure exerted on the jacketed part of the gasket. If such inserts are of plastic material, they cause better filling out and, as a result thereof, better sealing of the tool marks and grooves caused by machining and tooling the jacketing sheet metal. At the same time they increase the clamping pressure.
  • FIGS. 1 and 2 are cross-sectional views of the edge part of gaskets according to the present invention having only one leg of the jacket folded over.
  • FIGS. 3 and 4 are cross-sectional views of gaskets having both legs folded over.
  • FIGS. 5 to 8 are cross-sectional views of jacketed gaskets with inserts into the folded part or parts of the jacket.
  • FIGS. 9 and 10 are crosssectional views of folded jackets having inserts of plastic material.
  • FIG. 1 there is shown gasket 1 consisting of compressed asbestos with binder. Said gasket is jacketed at its edge by deep-drawing sheet iron enclosing and reenforcing the edge portion of the gasket on both its upper and its lower surface.
  • Upper extension or leg 10 of jacket 2 is folded over outwardly and forms outward fold 3. As is evident, said outward fold 3 is about half as wide as upper leg or flange 10 of jacket 2. It ends at a distance from the bend of jacket 2 corresponding to about part 3' of upper leg 10 is folded inwardly.
  • Lower legor, flange ll of jacket 2 ends at a distance about half the width of upper fold 3.
  • FIG. 2 shows the same jacketed gasket 1 whereby folded In FIG. 3 extensions or legslo and 11 ofjacket 2 are folded over outwardly on both sides of gasket 1.
  • Folds 3 and 4 have a width corresponding to about the thickness of gasket-l and end at a distance from the points atwhich jacket 2 is bent around gasket corresponding'toabout the thickness of gasket 1.
  • FIG. 4 shows the same jacketed gasket 1 whereby folded parts 3' and 4' at the upper and lower surface of said gasket 1 arefolded inwardly.
  • the distance of folds 3 and 4 or, respectively, 3' and 4' from thepoints at which jacket 2 is bent around gasket 1 is about the same.
  • FIG. 5 shows a jacketed gasket in which annular discor spacing washer 5 is inserted intothe fold between leg and folded'part 3; Said annular disc is not as wide as gasket 1 and Gaskets according to the present invention have proved to be especially suitable as cylinder head gaskets. They may, of 7 course, also be used for other packing and sealing purposes,
  • FIG. 6 shows a similar embodiment of the present invention as illustrated in FIG. 5 whereby both legs 10 and 11 of jacket 2 are folded to form folds 3 and 4any whereby annular discs 5 and 6 are inserted into the folds.
  • FIG. 7 illustrates an embodiment ,of this invention wherein not only jacket or bordering flange 2 is bent around gasket 1 but also insert 12 which is insertedwith its leg 7 between upper leg 10 and folded part 3 of jacket 2 and is bent'outloop 15 extending from lower leg '11 of jacket 2'.
  • Upper leg 10 is not folded.
  • Compressible plastic'material 9 is inserted in loop 15. It is partly squeezed out therefrom on compression 7 and thus covers and seals the turning grooves or tool marks 1 which might be present in lower leg 10/ FIG.
  • FIG. 10 shows a gasket 1 in which loops 14 and .15 are provided on upper and lower legs 10 and 11 ofjacket 2; Said loops are filled up with plastic inserts Qand 16 which are partly squeezed out on compressing the finished edgejacketed gasket.
